2 x 3 x 3 = 18
Assume you have 6 spots shown below: _ _ _ _ _ _ In the first spot, you have 6 letters to choose from. In the second spot, you have 5 letters to choose from because you already used one. Similarly, in the remaining spots, you will have 4, 3, 2, and 1 letters to choose from. So you have 6 choices * 5 choices * 4 choices * 3 choices * 2 choices * 1 choice = 720 possibilities
You can choose 5 different hats and for each of them 4 different sunglasses can be chosen, giving 5 x 4 = 20 different combinations.
You can choose 3 objects from 6 20 ways, assuming order does not matter
Since there are 3 numbers to choose from, there will be 2^3 = 8 combinations. This includes the null combinations which you may not wish to include in the count.
This principle simply tells us that if you have 2 choices to make, 1 from a list of m items and 1 from a list of n, the total number of ways to make the 2 choices is m times n. Similarly, if there are more than 2 choices, you just multiply the number of possibilities together. For example, if you have 4 choices for what your first child will wear today, 5 choices for the second, and 7 for the third, the total number of combinations is 4 times 5 times 7 which is 140. This assumes that the number of options for each choice is independent of the other choices you make. For example, if you must choose one direction to go one block in a city, and then another at the end of that block, but if you choose to go north in the first place you are at a dead end, but if you had gone south you could go 3 different directions, the principle does not apply because the number of options for the second choice depends on your first choice.
Subway sandwiches can be great because you can choose exactly which ingredients you do and do not want on your sandwich, and there are a lot of choices.

The number of different combinations in this case is simply the product of the three numbers.
5 is. (How many different ways are there for him to notchoose one of the five ?)
Assume you have 6 spots shown below: _ _ _ _ _ _ In the first spot, you have 6 letters to choose from. In the second spot, you have 5 letters to choose from because you already used one. Similarly, in the remaining spots, you will have 4, 3, 2, and 1 letters to choose from. So you have 6 choices * 5 choices * 4 choices * 3 choices * 2 choices * 1 choice = 720 possibilities
